note 23625 added to function.array-multisort

It can be very useful to use array_keys(*) as one of the arguments. Example: you have an associative array of items and quantities, where the item is used as a key. Say you want to sort the array by descending quantity, and sort items with the same quantity in alphabetical order. Here is the code: $arr["potato"] = 5; $arr["orange"] = 3; $arr["apple"] = 3; $arr["lemon"] = 4; $arr["onion"] = 5; $arr["grapefruit"] = 3; array_multisort ($arr, SORT_DESC, array_keys ($arr)); print_r ($arr); Here is the output: Array ( [onion] => 5 [potato] => 5 [lemon] => 4 [apple] => 3 [grapefruit] => 3 [orange] => 3 ) -- http://www.php.net/manual/en/function.array-multisort.php http://master.php.net/manage/user-notes.php?action=edit+23625 http://master.php.net/manage/user-notes.php?action=delete+23625 http://master.php.net/manage/user-notes.php?action=reject+23625
